def task_func(news_articles):
"""
Sort a list of news articles by "category" and "title." The news articles are then grouped by "category."
Parameters:
news_articles (list): A list of dictionaries where each dictionary represents
a news article with keys 'title', 'title_url', 'id', and 'category'.
Returns:
dict: A dictionary where the keys are categories and the values are lists
of articles sorted by 'title' in that category. Each article is represented as a dictionary
with keys 'title', 'title_url', 'id', and 'category'.
Raises:
ValueError: If dictionary keys do not match the requirements.
Requirements:
- collections.defaultdict
- operator.itemgetter
- itertools.groupby
Example:
>>> articles = [{'title': 'Apple News', 'title_url': 'Apple_News', 'id': 2, 'category': 'Technology'},
... {'title': 'New York Times', 'title_url': 'New_York_Times', 'id': 4, 'category': 'Sports'},
... {'title': 'USA Today', 'title_url': 'USA_Today', 'id': 6, 'category': 'Health'}]
>>> sorted_articles = task_func(articles)
>>> print(sorted_articles)
defaultdict(<class 'list'>, {'Health': [{'title': 'USA Today', 'title_url': 'USA_Today', 'id': 6, 'category': 'Health'}], 'Sports': [{'title': 'New York Times', 'title_url': 'New_York_Times', 'id': 4, 'category': 'Sports'}], 'Technology': [{'title': 'Apple News', 'title_url': 'Apple_News', 'id': 2, 'category': 'Technology'}]})
>>> articles = [
... {'title': 'Der Standard', 'title_url': 'standard', 'id': 2, 'category': 'climate'},
... {'title': 'tecky', 'title_url': 'tecky', 'id': 4, 'category': 'climate'},
... {'title': 'earth magazine', 'title_url': 'earth', 'id': 4, 'category': 'environment'}
... ]
>>> sorted_articles = task_func(articles)
>>> print(sorted_articles)

The function should raise the exception for: ValueError: If dictionary keys do not match the requirements.
The function should output with:
dict: A dictionary where the keys are categories and the values are lists
of articles sorted by 'title' in that category. Each article is represented as a dictionary
with keys 'title', 'title_url', 'id', and 'category'.
You should write self-contained code starting with:
